Gilead Teams Up With Kiniksa, Submits BLA for CAR T Therapy

Read MoreHide Full Article

Gilead Sciences, Inc.’s (GILD - Free Report) Kite and Kiniksa Pharmaceuticals, Ltd. (KNSA - Free Report) have entered a clinical collaboration to conduct a phase II, multicenter study on pipeline candidate mavrilimumab in combination with Yescarta.

We note that Gilead’s Yescarta was the first CAR T cell therapy to be approved by the FDA for the treatment of adult patients with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, primary mediastinal large B-cell lymphoma, and high-grade B-cell lymphoma and DLBCL arising from follicular lymphoma.

Mavrilimumab is an investigational, fully human monoclonal antibody that targets granulocyte macrophage colony-stimulating factor receptor alpha (GM-CSFRα). The combination study will be sponsored by Kite and conducted in patients with relapsed or refractory large B-cell lymphoma.

The objective of the study is to determine the effect of mavrilimumab on the safety of Yescarta.

Concurrently, Kite announced that it has submitted a Biologics License Application (BLA) to the FDA for the investigational CAR T cell therapy, KTE-X19, for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL).

The BLA was based on data from the phase II ZUMA-2 study, which demonstrated an overall response rate of 93%, including 67% with complete response, as assessed by an Independent Radiologic Review Committee following a single infusion of KTE-X19.

We remind investors that KTE-X19 has been granted Breakthrough Therapy designation by the FDA and Priority Medicines (PRIME) by the European Medicines Agency (EMA) for relapsed or refractory MCL.

Kite plans to submit a Marketing Authorization Application for KTE-X19 in the European Union in early 2020.

A potential approval will boost Gilead’s portfolio even though the competition is stiff in the CAR T therapy space from the likes of Novartis’ (NVS - Free Report) Kymriah.

Gilead’s stock has gained 8.4% in the year so far compared with the industry's growth of 6.3%.


The massive decline in sales of the HCV franchise has propelled the company to focus on its HIV franchise, Yescarta and other newer avenues. The rapid adoption of Biktarvy maintains momentum in the HIV space amid stiff competition from the likes of GlaxoSmithKline (GSK - Free Report) . Gilead’s intent to foray into the inflammation market to diversify the revenue base is encouraging as well.    

Gilead currently carries a Zacks Rank #3 (Hold). You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.
